Wrong safety checksum

What does F01660 mean?

This fault occurs when checksums related to safety commissioning are inconsistent, preventing the drive from exiting the commissioning state. This indicates that safety parameters in p9798, p9799, p9898, or p9899 do not match as required, signaling a configuration error that must be resolved for safe operation.
